Grade 6 Math Quiz on Integers and Coordinate Plane - Term 2

Let’s solve each problem one by one, step by step.

---

1. Write –12/25 as a decimal.

We divide 12 by 25:
12 ÷ 25 = 0.48
Since it’s negative: –0.48

✔ Correct answer: B. –0.48

---

2. Which of the following is a true statement?

Check each option:

F. –5/6 > –4/9 → Convert to decimals:
–5/6 ≈ –0.833, –4/9 ≈ –0.444 → –0.833 is NOT greater than –0.444 → False

G. 4.3 > 4 3/4 → 4 3/4 = 4.75 → 4.3 < 4.75 → False

H. 13 5/8 = 13.625 → 5/8 = 0.625 → 13 + 0.625 = 13.625 → TRUE ✔

I. 5/9 > 0.57̅ → 5/9 = 0.555..., 0.57̅ = 0.5777... → 0.555 < 0.577 → False

✔ Correct answer: H

3. Trent made 11 free throws out of 15 attempts. What was his average as a decimal?

11 ÷ 15 = ?

Do the division:
15 into 11.000 → 0.7333... → repeating 3 → 0.7̅3̅? Wait — actually:

11 ÷ 15 = 0.7333... = 0.7̅3? No — let's compute carefully:

15 × 0.7 = 10.5 → remainder 0.5
0.5 ÷ 15 = 0.0333... → so total = 0.7333... = 0.7̅3? Actually, standard notation: 0.73 with bar over 3 → 0.7̅3 is not standard; usually we write 0.73̅ meaning 0.7333...

Looking at options:

A. 0.7 → too low
B. 0.7̅3 → probably means 0.7333... → correct
C. 0.3̅7 → no
D. 0.8̅ → no

Actually, 11/15 = 0.7333... = 0.7̅3 if they mean the 3 repeats — but in math notation, we usually put the bar over the repeating digit(s). So 0.7333... = 0.7̅3? Not standard — better to say 0.73̅ (bar over 3).

But looking at the options: B is written as “0.7̅3” — which might be a typo or misnotation. But among choices, only B makes sense.

Wait — let me recalculate:

11 ÷ 15:

15 ) 11.000
10.5 ← 15×0.7
----
0.50
0.45 ← 15×0.03
----
0.050
0.045 ← 15×0.003
-----
0.005 → continues → so 0.7333... → yes, 0.73̅

Option B says “0.7̅3” — that would imply 0.737373... which is wrong. Hmm.

Wait — maybe it’s a formatting issue. In some fonts, “0.7̅3” might mean 0.7333...? Unlikely.

Let me check exact value: 11/15 = 0.7333... = 0.7 + 1/30 = but anyway.

Perhaps the bar is over the 3 only? The way it’s printed: “B. 0.7̅3” — likely a typesetting error, and it should be 0.73̅.

But let’s look again: Option D is 0.8̅ — too big. C is 0.3̅7 — nonsense. A is 0.7 — too small.

So even if notation is off, B is intended to be 0.7333...

Alternatively, maybe “0.7̅3” means 0.7333...? In some systems, they put bar over first repeating digit.

Actually, standard is to put bar over all repeating digits. Since only 3 repeats, it should be 0.73̅.

But given the options, B is the closest and intended answer.

Wait — let me calculate numerically:

11 ÷ 15 = 0.733333... → so decimal is 0.73 with 3 repeating → written as 0.73̅

In the quiz, option B is written as “0.7̅3” — this is ambiguous, but perhaps it’s meant to be 0.73̅. Maybe a font issue.

Alternatively, perhaps I miscalculated?

No — 11/15 = 0.7333... definitely.

Another thought: sometimes people write 0.7̅3 to mean 0.7333...? Not standard, but possible in context.

Given that, and since other options are clearly wrong, we go with B.

But wait — let me see the original image text: “B. 0.7̅3” — in LaTeX or plain text, this might render as 0.7 with bar over 7 and then 3? That would be 0.777...3? Nonsense.

Perhaps it’s a typo, and it’s supposed to be 0.73̅.

Looking back at question 1: they have “C. 2.0̅8” which likely means 2.0888...? Or 2.08 with 8 repeating? Usually bar over last digit.

In question 1, –12/25 = –0.48 exactly, so no repeat.

For 11/15, it’s 0.7333... so repeating 3.

I think the intended answer is B, assuming “0.7̅3” is a misprint for 0.73̅.

To confirm: 11/15 = 0.7333... = 73.333...% → yes.

So I’ll go with B.

4. Which set of rational numbers is ordered from least to greatest?

We need to compare the numbers in each option.

Start with F: –4.3̅, 4 1/4, 4 1/5, 4.06

–4.3̅ = –4.333...
4 1/4 = 4.25
4 1/5 = 4.2
4.06

Order: –4.333, then 4.06, then 4.2, then 4.25 → but listed as –4.3̅, 4.25, 4.2, 4.06 → not sorted → false

G: –0.27, –2/9, –2/3, –0.1̅

Convert to decimals:

–0.27
–2/9 ≈ –0.222...
–2/3 ≈ –0.666...
–0.1̅ = –0.111...

Now order from least to greatest: most negative to least negative.

–0.666... (–2/3), then –0.27, then –0.222... (–2/9), then –0.111... (–0.1̅)

But the set is listed as: –0.27, –2/9, –2/3, –0.1̅ → which is –0.27, –0.222, –0.666, –0.111 → not sorted → false

H: –6 5/8, –6.34, –6.3̅, –6 1/4

Convert:

–6 5/8 = –6.625
–6.34
–6.3̅ = –6.333...
–6 1/4 = –6.25

Now order from least to greatest: –6.625, –6.34, –6.333..., –6.25

Listed as: –6.625, –6.34, –6.333..., –6.25 → YES! This is increasing order.

Check: –6.625 < –6.34 < –6.333... < –6.25 → true because –6.34 is more negative than –6.333...

–6.34 = –6.340, –6.333... = –6.333, so –6.340 < –6.333 → yes.

And –6.333 < –6.25 → yes.

So H is correct.

Just to check I: –7 12/13, –7 13/15, –7.86̅, –7.86̅ (wait, two same?)

–7 12/13 ≈ –7.923
–7 13/15 ≈ –7.866...
–7.86̅ = –7.8666...
–7.86̅ again? Probably typo, but anyway.

–7.923, –7.866, –7.866, –7.86 → not strictly increasing, and duplicates.

But H is clearly correct.

✔ Answer: H

8. What is the opposite of –17?

✔ Answer: G. 17

9. Which set of integers is graphed on the number line?

Number line shows points at: –4, –2, 1, and also 0? Let me see description.

The number line has marks from –4 to 4.

Points plotted: at –4, –2, 1, and also at 0? The description says: "graphed on the number line" and lists options.

From the text: "Which set of integers is graphed on the number line?" and then a number line with dots.

Assuming from standard interpretation: if dots are at –4, –2, 1, and possibly others.

Looking at options:

A. {–4, –2, –1}
B. {–4, –2, 1}
C. {–4, –1, 2}
D. {–4, 1, 2}

If the number line has dots at –4, –2, and 1, then B is correct.

Also, is there a dot at 0? The problem doesn’t specify, but typically in such questions, only marked points are included.

Assuming the graph shows points at –4, –2, and 1 (since those are common), then B.

To confirm: if it were including 0, it would be in options, but none have 0 except possibly implied.

Option B is {–4, –2, 1} — likely correct.

✔ Answer: B
